Hi,

Does someone have feedback on the power difference, if there is one, between running a twin plug distributor with 1 or 2 MSD - 6420 box ??

I will have a Aaron-Rennwerks distributor with two 8222 MSD coil, I already have a 6420 box, I'm hesitating in buying another one or not ?!

Thanks for your feedback !

Regards
JD
